Hey, any good ideas on building a gismo to setup forward/reverse to servo on a Graham TVR1A-BB. Building a new boat and thought I would get a head-start on where to place the servo in relationship to the forward/reverse mechanism.

Look at post #102 (Return of Clever Lever)

Not my post.  However, it shows the mod needed.

DocMartin,


Thanks for this - I talk to Carl Miller once a week maybe more, but never thought to ask him.
Thanks for the heads up - this is perfect.

As a follow-up to my question for a forward and reverse for my TR1A-BB. An engineer boat club buddy (Mark Montgomery) took Carl Miller's idea and made a bell crank for me.

Works great on air, will try with steam shortly. — https://www.morfa.ca/Bellcrank2023.mp4
He produced some great diagrams for those who wish to do it themselves - great boat builder too.


Thanks for everybody's help

Missed this the first time - sorry! - but there is another way to operate the forward/reverse lever, but it is done from the other side of the engine.  If you look at this video, you will see that the forward/reverse lever is extended to the other side of the engine and has a brass lever mounted on it.  A servo (hidden in the video) then pushes/pulls that lever to operate the reverse mechanism.  However, if you are already set up, feel free to ignore all this!

Happy steaming

Greg,
Very neat indeed. Very simple. As I have already Macgyvered it, by a very nice boat engineer friend.
Will keep this method in my back pocket - thanks for it
